HENRY O. HERE, OF DETROIT, MICHIGAN.

APPARATUS FOR MANUFACTURING MULTIPLY PAPER-BOARD.

Application filed April 22,

To all whom it may concern:

Be it known that I, HENRY C. linen, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Apparatusfor Man ufacturing Multiply Paper-Board, of which i the following is aspecification, reference being had therein to the accompanying drawmgs.

The invention relates to apparatus for forming paper board from aplurality of plies of paper, and it is the object of the invention toprovide means whereby strips of paper of considerable length may beaccurately registered with each other, and firmly united to form theboard.

To this end, the invention consists in certain features of constructionas hereinafter set forth.

In the drawings, Figure 1 is a sectional side elevation of the machine;Fig. 2 is a plan view and Fig. 3 is a diagram illustrating the principleinvolved in the construction of the machine.

Where two paper stri )s are united by being pasted and then fe intocontact, it is difficult to form a perfect union. The difficultiesencountered are, first, that the strips will not feed in perfectalinement and consequently, after once being attached, the greater thelength which is fed, the more they will be out of registration. Ifguiding devices are employed for limitin the lateral deflection of thestrips, these wi 1 only result in causing them to buckle and produce ablister or imperfect union wherever any correction in the direction offeed is made. With my invention, 1 overcome this difficulty, first, byalining all of the several strips before feeding the same into contactwith each other second, by separately adjusting each of the strips to asurface a ainst which they are pressed when united; t iird, in providingfreedom to each of the successively applied strips to adjust itself tothe strip previously laid in contact with the holding surface; fourth,in applying the paste to the surface of the strip last lald and whichadjusts itself to the previously laid strip; fifth, in effecting theunion of the strips during the reeling of the same upon a roll; andsixth, by feeding the diflerent strips tangentially to difiierent pointsin the circumference of the rec As illustrated, A is a suitable framework,

upon which is mounted a plurality of paper feeding and guiding devices13 B. Each of these preferably comprises a bed or table 0, a pluralityof rolls D D for straightening the strips in contact with said table,and edge guides E for determining the line of feed. The several guidingdevices B B are alined with each other, so as to aline the stripsrespectively fed therethrough, and each is preferably further rovidedwith a pair of rand-feeding rolls 1* F operated by a hand wheel G, bymeans of which the strip may be easily fed until its end is attached tothe reel.

In the frame A is a reel H preferably comprising the roller journaled inhearings in the frame, and revolved through the medium of suitable driveconnections, such as the pulleys I and belt J leading to a pulley on thedrive shaft K. The reel H is accurately positioned, so that the severalstrips from the guiding devices B B will be fed tangentiallytherethrough. The point of tangency of each of the several strips isseparated from that of the other strips, and thus the reel passesthrough a greater or less angle before one strip wound thereon iscovered by another strip. This permits the first stri contacting withthe reel to adjust itself t ereto before its movement is imparted by thepressure of a succeeding strip. As a consequence, each succeeding stripwill perfectly adjust itself in contact with the strip wound in advancethereof, so as to produce a perfect contact.

To unite the strips, one surface of each pair is pasted and the adhesivematerial is preferably applied to the under surface of thepasted strip.The mechanism for accomplis mg this is illustrated in Fig. 1 ascomprising a roll L rotating in the paste tank M, and in Workingposition projecting between two idler rolls N and N. The paper strip isthus caused to pass around a segment of the roll L, which applies thepaste uniformly to the entire surface of the strip. The paste tank isconstantly supplied with paste or inhesive b circulating conduits O andO and a pump driven by the drive connection Q on the shaft K, but thismechanism forms no part of the present invention.

1 With the construction described, in operation each of the several stris is first passed over the table C of its ui e device, and is then fedby the hand-r0 1 F until the end of the strip is secured to the reel H.ment is then imparted to the reel, which will draw all of the stripssimultaneously and wind them thereon. The pasted strips R, as indicatedin Fig. 1, does not contact with the reel until the other strip S hasbeen wound thereon and also adjusts itself in perfect contact with theroll. Furthermore, the point of tangency of this pasted strip being searated from the point of tangeney of t 1e strip S, it will adjust itselfinto perfect contact before being covered and held from movement by thesucceeding convolution.

In Fig. 3, I have illustrated diagrammatically a similar apparatus, inwhich a larger number of strips is used, and in which the several stripsare all tangent to the reel, but from spaced points and in itscircumference.

It will be observed from the dotted lines in Fig. 1 that the separationin points of tangency of the two strips continues as the reel increasesin diameter by the added convolutions thereof.

In addition to the function of first feeding the paper through theguides to the reel, the rolls I F erform the function of a resistancefor p acing a tension upon the paper stri Furthermore, as these rollsare placed in t e center of the guides, the alineinent of the strip isnot interfered with. As the paper strip is preferably fed to the guidesfrom a free roll, it is permitted to perfectly aline itself with theguides, and as each of the guiding devices is in perfect alinement withthe ot er, the strips, when delivered to the reel, will be in erfectregistration.

What claim as my invention is:

1. The combination with a reel, of a frame in which said reel isournaled and a plurality of guides for feeding separated pa er stripstangentially to said reel .and with t eir edges in the same lane, eachof said. guides comprising a tab e, a plurality of rolls for holding thepaper strips 1n contact with said table, edge uides for said strips andan intermediate ro lfor placing africtional resistance upon the strip.

2. A paper strip alining mechanism, comprising a plurality of parallellyarranged tables over which the strips are fed, rolls for holding thestrips in contact with said tables and an intermediate roll for placingfrictional resistance upon the strip.

3. The combination with a reel, of a frame in which said reel isjournaled, and a plurality of guides for feeding separated pa er stripstanglentially to said reel and with t ieir edges in t e same .lane, eachof said guides com prising a tab e, a plurality of rolls for holding thepaper strips in contact with said table, and edge guides for saidstrips.

4. The combination with a reel, of a frame in wln'ch said reel isjournaled and a plurality of guides for feeding separated pa er stripstangentially to said reel and with tffeir edges in the same plane, eachof said guides com prising a table and a plurality of rolls for ioldingthe paper strips in contact with said table.

5. The combination with a reel, of a frame in which said reel isjournaled and a plurality of parallel guides for feeding separated paperstrips tangentially to said reel.

6. The combination with a reel, of a frame in which said reel isjournaled and a plurality of arallel tables each provided with guider011 for holding the pa er strips in contact with the table, for feeringseparated paper strips tangentially to said reel.

7. The combination with a reel, of means for feeding a plurality of stri)S tangentially to said reel, means associated with said reel forpressing said stri s into contact, and means intermediate tie reel andfeeding means for maintaining the edges of the several strips in thesame plane.

8. The combination with means for pressing together and uniting aplurality of pasted paper stri s, a plurality of means positioned 1nparalle lanes for feeding the several stri s to sai uniting means, andmeans for gui ing said strips into actualalinement with each other inadvance of their delivery to said uniting means.

In testimony whereof I affix my signature in presence of two witnesses.
